Last week I heard a Gray Catbird singing vociferously along with more than one more muted robins at 3:30 am. I was surprised as I have had catbirds nesting in my yard and neighborhood for several years and never heard this before. I fell back asleep to a catbird serenade. >From *Birds of North America *online: "Daily Pattern Of Vocalizing In morning, male begins singing 30 min or more before civil twilight (Slack 1973<http://bna.birds.cornell.edu/bna/species/167/articles/species/167/biblio/bib095>); continues throughout day, with greatest frequency in morning and evening, slightly lower in afternoon (Harcus 1973<http://bna.birds.cornell.edu/bna/species/167/articles/species/167/biblio/bib044>). Sometimes sings at night (Gross 1948<http://bna.birds.cornell.edu/bna/species/167/articles/species/167/biblio/bib042>, Graber et al. 1970<http://bna.birds.cornell.edu/bna/species/167/articles/species/167/biblio/bib040> )."
